I'm debating whether i want to continue waiting on the DX9 or buy a Firewire External Case. I notice most cases are fanless and just use aluminum to disapate the heat. I have this type for my Windows PC but that HD does not stay on long just when I need to grab a file. I'd most like be running my Mini's External Drive all the time I'm using my Mini so Heat worries me. Any enclosures you guys recommend Fanless or otherwise, and has anyone hear anything about the DX9 ? I have a 400GB Seagate IDE drive I need to enclose.

I ended up ordering the Mercury Elite from OWC for $68 it's not that much that if I wanted to get the DX if they ever release it, I still could. I understand from what I read these are pretty decent. I notice it's got Auto Switching what exactly will that do for me?
